D A N G E r
• Check to ensure that the accessories are packed with the
indoor unit.
• Do not install the indoor units outdoors. If installed out-
doors, an electric hazard or electric leakage will occur.
• Consider the air distribution from each indoor unit to the
space of the room, and select a suitable location so that
uniform air temperature in the room can be obtained. It is
recommended that the indoor units be installed 2.3 to 3
meters from the floor level. If the unit is installed higher
than 3 meters, it is also recommended that a fan be utili-
sed to obtain uniform air temperature in the room.
• Avoid obstacles which may hamper the air intake or the
air discharge flow.
• Pay attention to the following points when the indoor
units are installed in a hospital or other places where the-
re are electronic waves from medical equipment, etc.
• Do not install the indoor units where electromagnetic wave
is directly radiated to the electrical box, remote control cable
or remote control switch.
• Prepare a steel box and install the remote control switch
in it. Prepare a steel conduit tube and wire the remote
control cable in it. Then connect the ground wire with the
box and tube.
• Install a noise filter when the power supply emits harmful
noises.

• This unit is exclusive non electrical heater type indoor
unit. It is prohibited to install a electrical heater in the
field.
• Do not put any foreign material into the indoor unit and
check to ensure that none exist in the indoor unit before
the installation and test running. Otherwise a fire or failu-
re, etc., may occur.
C A u T I O N
• Do not install the indoor units in a flammable environment to
avoid a fire or an explosion.
• Check to ensure that the ceiling slab is strong enough. If not
strong enough, the indoor unit may fall down on you.
• Do not install the indoor units in a machinery shop or kitchen
where vapor from oil or mist flows to the indoor units. The oil
will deposit on the heat exchanger, thereby reducing the indo-
or unit performance, and may deform. In the worst case, the
oil damages the plastic parts of the indoor unit.
• To avoid any corrosive action to the heat exchangers, do not
install the indoor units in an acid or alkaline environment.
• When lifting or moving the indoor unit, use appropriate slings
to avoid damage and be careful not to damage the insulation
material on units surface.
